You're welcome Michael, glad the vids are helping you.

Thanks John, good luck with your motor!

Great to hear!

Thanks mate!

Thanks mate, sorry to hear you had a bad day but glad to hear the vids are helping. :)

Thanks mate. Yes, just because you've found "a problem" doesn't mean you've found "the problem"!

Thanks Sean, glad you enjoyed it.

Thanks mate, glad to hear you've been enjoying the vids, particularly that early in the morning!

Thanks Chris, glad the vids have been helping you. :)

Thanks Dennis! :)

Hey mate, glad you have joined us and are enjoying the vids. Good luck with your Evinrude rebuild. :)

Thanks mate. Sounds like he is taking a good route with his fuel tanks, I don't think he'll regret the change.

You're welcome mate, glad you've been enjoying them. :)

Glad the video helped. :)

For sure. The fuel we buy from water-front marinas certainly doesn't help either.

Thanks mate, glad the videos have been helping you. Good luck with your shop, I know exactly how hard it can be to keep a small shop open and profitable.

Hey Ron, yeah, it's pretty much the same for all two stroke motors. It is nice to know that once you figure one out you are good to go for all the others.

Hey Bruce. I'm thinking I'll test the ignition first, mostly as I think it will be easier and doesn't involve taking the powerhead off. Fingers crossed that is all there is to it.

Looking forward to that Stu, as they say, do the easy stuff first as 90% of the time that is where the problem is. But this one has got me scratching my head too. Roll on next weekend! By the way it was your videos on checking the IGN circuits that led me find the problem on mine.

You're welcome Martin. :)

Thanks Chris, glad the vids have been helping you. :)

Thanks mate, glad you liked it. :)

Thanks Tim, great to hear your outboard is running sweetly now. :)

You just need a new engine anything pre 2000 is a right off.

I've never had to replace a set yet either which is why I don't often suspect them. I'm not sure what it would take for them to fail, even in these old saltwater motors they always seem fine.

Hopefully it will be at least diagnosed by the next video, even if it means waiting for parts.

Nice work, glad it turned out to be something simple. :)

Dangar Marine yah, me too!

Thanks mate, glad you enjoyed the vid. :)

I don't always explain it the best though! ;)

Good news! :)

Was it reeds

@@hiimtoxic9518 Nope. Took it out today after completing a full rebuild in all 3 carbs and it ran like a brand new motor. Everything was clogged. The jets, the needle seat in one carb was so bad you couldn't see light through. All the small ports were clogged. It was bad.

Glad it was helpful!

Thanks mate, we'll see soon enough. We should have a vote. ;)

Me too!!!

Thanks mate, glad the vids have been helpful. Yes, having a correct float level is very important to get the correct mixture.

You're welcome Don, good luck!

Thanks mate!

Yes, it can take quite a while to find the problem some times but it's always satisfying when you do!

Glad you like them!

WME carbys flooding! Other than reed valve failing what's most likely cause for this issue? Thanks in advance

Thanks Chris!

Hey Eric, I did have a play with the mixture screws and they seem to be set fine, but I'm going to go through a whole range of mixture / choking / sparing fuel to test which is lean in the next vid.

It could be as simple as the throttle cable creeping back. If not I would make sure the fuel pump can supply enough fuel, it may not be able to keep the carbs full.

Carb clean first then look at other stuff.

Thanks mate. :)

There are definitely some jobs that leave you scratching your head, that's for sure. We've got plenty of things to check on this outboard yet though! ;)

Will do! :)

@@Mad-Coo Motor has been sold. But, i did fix the issue by flipping the reeds and got rid of the little gap. Replaced missing rubber retainer for the adjustment screw in front of carb right above the intake while because it would rattle lose each time I speed up. Ran great from there on out.

Ah, interesting about some bikes having rotary valves, I'll have to look into those. From what I hear the shape of the exhaust after the port is critical with 2-strokes too to get the gasses extracted efficiently.

Keep in mind that the transfers are effectively the intake valves for the cylinder when compared to a 4 stroke.. Where the 2 stroke intake is the intake to the crank case not the cylinder. Transfers mostly influences mid range power up to peak, once a 2 stroke is at peak it tends to over scavenge so much intake spills from the exhaust port, hence an exhaust provides back pressure to plug escaping intake charge at peak. One important moment is blow down time which is the period the exhaust is open for and transfers not yet open when initial cylinder pressure blows down out the exhaust. A piston port intake timing has symmetrical so opening and closing is equal degree from TDC like exhaust and transfers, all controlled by piston. The disc valve is asymmetric so intake opens a lot earlier that allows the crankcase to equalise pressure through the carby instead of back flowing down the open transfers as the piston is rising. The reed valve timing is like a disc valve timing at low revs opening very early and then like a piston port at high revs, so the opening point in degrees gets later as engine speed increases, so rotary disc has an advantage in smaller engines due to less gas inertia where reed is as good as disc over about 150 cc per cylinder..

Ha! That's certainly a nice easy way to go. ;)

Thanks Jonathan, you are dead right about there being lots of value in showing the wrong turns along the way.

Thanks!

You're welcome, thanks for the beer! :)

You're welcome. :)

Yes, it can cause the cylinder to run lean and get hot.

Gracias compañero, me alegro de que disfrute de los videos.

It could be leads but in the end this outboard turned out to have a problem with the carburettors not being synchronised ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NnotQmnKxKM.html

You're welcome Angelo. :)

You're welcome John.
